OFFICE v METHOD OF LUBRICATING TEXTILE MACHINERY No Drawing.

This invention relates to improvements in the lubrication of bearingsand other moving parts of machines used in the fabrication of textiles.As is well known, it is practically impossible to prevent soiling of thetextile product by the 'oil or grease used on difficulty has been met insecuring a lubricating material which has satisfactory lubricatingqualities and is also readily washed out of the textile product.

In accordance with the present invention, textile machines and theirappurtenances are lubricated wth a viscous hydrocarbon oil containing asmall percentage of water-solsulphuric acid or contact uble soap. Iprefer to use a petroleum oil of about 50.to 2.50 seconds Sayboltviscosity at 100 F., highly purified by treatment with with fullersearth or the like or by-any other methods known to the petroleumindustry and containing about 0.15% to 1.5%

metal soap of one or ty acids; for example, sodium oleate orsodistantially neutralize the oleic .suitable way, examples of PatentNo. 1,628,646,

not less than 350 um stearate, or mixtures of the same. For spindlelubrication, oils of 50 to 100 seconds Saybolt, viscosity are mostsuitable, while for motor bearings and the like 75 to 250 viscosity at100 F., or even higher, is desirable. The quantity of soap in oil foreither purpose is generally between .1-5 and 20%.

The composition may be prepared in any which are de scribed inapplicants patented May 17, 1927. In one process formaking thecomposition, a mixture of viscous petroleum oil and theproper percentageof oleic acid is brought up to a temperature of by weight of an alkalimore of the higher fat textile Application filed September 20, 1926.Serialv No. 136,721.

the fibers, nor have any disagreeable odor. The so-called white oils areparticularly well adapted for this purpose. White oils are highlypurified heavy petroleum oils,

corresponding more or less closely to petrolatum liquidum, U. S. P.However, the present method is not limited to the use of such oils. Forexample, oils of the ordinar lubri eating grade may be used, especiallyin cases Where some coloration is not objectionable.

The lubricants described above are applied to the bearingsand otherparts in the usual manner.

Various changes and alternative procedures may be adopted within thescope. of
